The amphibians that live in the Canary Islands consist of two species.
Both the Mediterranean tree frog and the Iberian green frog were introduced by humans in the 15th century in order to control crop pests.
Between 1985 and 2015 there was a population of the Sahara frog on Gran Canaria, which has since disappeared, but hybridization with the Iberian green frog would have been possible.
